Folks,
I've been a VMware user for a long time. However after having various
issues running vmware under F43 I decided this was an opportune time to
learn about KVM. So I ran:
[pgaltieri@terrapin ~]$ virt-host-validate
QEMU: Checking for cgroup 'devices' controller support
: WARN (Enable 'devices' in kernel Kconfig file or mount/enable
cgroup controller in your system)
.
.
.
QEMU: Checking for secure guest support
: WARN (Unknown if this platform has Secure Guest support)
.
.
LXC: Checking for cgroup 'devices' controller support
: FAIL (Enable 'devices' in kernel Kconfig file or mount/enable
cgroup controller in your system)
LXC: Checking for cgroup 'freezer' controller support
: FAIL (Enable 'freezer' in kernel Kconfig file or mount/enable
cgroup controller in your system)
I've googled the issue and I get different responses. The one I used is
GRUB_CMDLINE_LINUX="rhgb quiet intel_iommu=on cgroup_enable=devices
systemd.unified_cgroup_hierarchy=0"
in /etc/default/grub
even after doing the
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
and rebooting I still get the FAIL for cgroup devices and freezer.
I even tried with systemd.unified_cgroup_hierarchy=1 with the same
result. What do I need to do to resolve these failures?
Any help is appreciated.
Paolo
